808529 ÷ 40 
Our goal is to divide 808529 by 40.

Advancing to step 1:
The number 40 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 40

Going ahead to step 2:
80 divided by 40 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 80 from 80, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 40

On to step 3:
8 divided by 40 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 40

On to step 4:
40 goes into 85 2 times with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 202.0
The remainder is 5 after subtracting 80 from 85.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 40

Let's proceed to step 5:
If we divide 52 by 40, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 2021.0
If we subtract 40 from 52, we get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 40

Step 6:
40 goes into 129 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 20213.0
Subtract 120 from 129 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
40 can be fit into 90 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 20213.2
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 40, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 20213.22
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 20213.22, with a leftover of 0.02.
